I have a table with records like this

      CID S TO_CHAR(DATECREATED, MESSAGE                     PID
--------- - -------------------- -------------------- ----------
        2 N 01-feb-1974 19:45:45 service change                1        *
        3 N 01-feb-1974 19:45:45 service change                1        *       
        3 N 01-feb-1974 21:45:45 service change                1
        1 N 01-jan-1974 12:34:45 msisdn change                 1        *
        1 N 01-jan-1974 19:45:45 service change                1
        2 N 01-jan-1974 19:45:45 service change                1
        1 N 01-nov-1974 17:45:45 service change                1
        1 N 01-nov-1974 19:45:45 service change                1


       

I want to display only the records with the *(not a value stored in the database.just used as a marker here).
i.e the records which meet the following.

1.earliest date
2.if there are multiple occurances of records with the same cid and pid combination i want only the record for
the combination of cid-pid and with the most earliest record(oldest time stamp).

i want to achieve this

      CID S TO_CHAR(DATECREATED, MESSAGE                     PID
--------- - -------------------- -------------------- ----------
        2 N 01-feb-1974 19:45:45 service change                1        *
        3 N 01-feb-1974 19:45:45 service change                1        *       
        1 N 01-jan-1974 12:34:45 msisdn change                 1        *

I need some help in getting the query that can get the results like that.

Thanks
